Embodiment Construction

[0035] figure 1 A ram air channel 2 with an air inlet 4 and an air outlet 6 is shown. The air inlet 4 includes an air inlet flap (not shown) by which the amount of air entering the air inlet 4 can be controlled. The air inlet 4 is preferably of NACA form. The air outlet 6 comprises an air outlet flap 18 . A heat exchanger 10 of the cabin air conditioning system is arranged in the ram air duct 2 . As mentioned earlier, the cabin air conditioning system controls the temperature of the cabin and cabin and sets the pressure in the cabin and cabin during flight to substantially correspond to the air pressure on the ground. The heat exchanger 10 may comprise a main heat exchanger and / or a primary heat exchanger of a cabin air conditioning system. The heat exchanger 10 cools hot engine bleed air, for example. The air cooled by the heat exchanger can be passed into the nacelle after further conditioning.

Abstract

The invention concerns a cooling system for an aircraft with an air inlet (4) through which air from the environment of the aircraft enters a ram air channel (2), and an air outlet (6) through which air emerges from the ram air channel (2). A heat exchanger (10) is arranged in the ram air channel (2). A ventilation device (8) is in fluid communication with the ram air channel (2). Also connected to the ram air channel (2) is a distribution line (12) to cool at least one heat-loaded component of the aircraft, in particular a cabin air conditioning system, and / or to ventilate an installation space of the at least one heat-loaded component.

Description

technical field [0001] The invention relates to a ram-air-based cooling system for an aircraft, with which a heat exchanger of a cabin air-conditioning system and at least one further component of the aircraft are supplied with cooling air, and / or the installation of said components The space can be ventilated. The component may be a component of the cabin air conditioning system. Background technique [0002] In aircraft, cabin air conditioning systems are used to supply fresh and recirculated air to the cabin and cockpit. In addition, the cabin air-conditioning system must also ensure that during high-altitude flight, a pressure that substantially corresponds to the air pressure on the ground occupies the cabin and cockpit. The cabin air-conditioning system is used as an air source for blown air from the engine or from, for example, an auxiliary engine (auxiliary power unit (APU: auxiliary power unit)) which may be arranged at the rear end of the aircraft. The temperatu...
